It is essential for generating the synthetic image to test and evaluate a guided missile system in the hardware-in-the-loop simulation. In order to make the evaluation results to be more reliable, the extent of fidelity and rendering performance of the synthetic image cannot be left ignored. There are numerous challenges to simulate the LWIR sensor signature of sea surface depending on the incident angle, especially in the maritime environment. In this paper, we investigate the key factors in determining the apparent temperature of sea surface and propose the approximate formula consisting of optical characteristics of sea surface and sky radiance. We find that the greater the incident angle increases, the larger the reflectivity of sea surface, and the greater the water vapor concentration in atmosphere increases, the larger the amount of sky radiance. On the basis of this information, we generate the virtual maritime environment in LWIR region using the SE-WORKBENCH, physically based rendering software. The margin of error is under seven percentage points.

Purpose: The present study was to investigate sleep disturbance and related variables in patients undergoing hemopoietic stem cell transplantation(HSCT) on the day of admission, before HSCT, and of discharge, respectively. Method: A total of 52 HSCT patients were recruited from an university hospital from August 2002 to August 2003. The patients were asked to complete a set of sleep disturbance questionnaires. Result: The scores of sleep disturbance-related physical and emotional subscales on the day before HSCT and on the day of discharge were significantly higher than that on the day of admission. However, the score of a emotional subscale was not significantly different during the hospitalization for HSCT. About 10% of the variance of sleep disturbance was explained by the length after diagnosis on the day of admission, and 59.4% was by the type of disease, religion, gender, educational level on the day before HSCT. About 40.7% was by family income, gender, and the frequency of administration on the day of discharge. Conclusion: Nursing staffs should care for HSCT patients with more interest to reduce variables disturbing sleep. Especially, more careful nursing interventions have to be considered at the time of the day before HSCT and the time of discharge.

The purpose of this study was to investigate the present state of e-business according to the establishment year and the sales approach of Dongdaemun clothing market and to present problems according to e-business activation of it and its developmental direction. The subjects for this study were selected out of Dongdaemun clothing markets being considered as more fashion-oriented markets and were divided into two categories both according to the establishment year and according to the sales approach. As a result, Dongdaemun clothing markets are mainly divided into traditional wholesale market, eastern wholesale & retail market, and western retail market and having dealings with each other according to the market`s characteristics. The utility percentage of on-line e-business according to the establishment year and the sales approach showed that traditional wholesale market was 42%, eastern wholesale & retail market 0.75%, and western retail market 11%. This result indicated that the utility percentage of traditional wholesale market showed much higher than eastern wholesale & retail market and western retail market. This would be because the structural characteristics of clothing market delayed the utility of e-business. For the problems on the utility of on-line e-business through counselling, traditional wholesale market showed much higher than wholesale & retail market and retail market because it had little problems on design imitation in retail market due to export by order and mass production. The problems of low utility of on-line e-business in Dongdaemun clothing market would result from well-timed on-line update according to rapid goods cycle, constant satisfaction for additional order, standardization of size and quality, and inexpensive internet purchase despite of express expense.

Several basic components of the fuel cell system for ships include a fuel cell stack, a power conversion system, a battery, and a control device. Polymer electrolyte membrane fuel cell(PEMFC) is considered the most important component in this system as it has a variety of advantages such as high-power density, fast response speed, and low operating temperature. However, a stable, high-efficiency boost converter must be manufactured to utilize it as a power source for ships due to several drawbacks like low voltage and a wide range of fluctuation and high currents. This paper aims to study the design and implementation of a high-current power conversion system utilizing an insulated resonance converter for the fuel cell system for ships. The proposed power converter in this study consists of a two-stage conversion structure, which incorporates a two-phase interleaved boost converter and a series resonance converter(SRC). The performance of the structure is verified by testing a 30 kW class unit module manufactured.

박혜령(Hye-Ryung Park),서형주(Hyung Joo Suh),유광원(Kwang-Won Yu),김태영(Tae Young Kim),신광순(Kwang-Soon Shin) 한국식품영양과학회 2015 한국식품영양과학회지 Vol.44 No.5

녹차 성숙잎으로부터 새로운 면역 활성 다당 소재를 개발할 목적으로 녹차잎을 pectinase로 처리하여 조다당 GTE-0을 분리하고 이들의 면역증진 활성과 화학적 특성에 대해 조사하였다. GTE-0은 중성당 54.9%, 산성당 45.1%로 이루어져 있었으며, 구성당 분석 결과 주로 glucose(14.2%), arabinose(12.2%), rhamnose(11.1%) 및 galactose(7.3%)로 구성되어 있었다. 한편 GTE-0은 비특이적 면역계에 있어 중요한 역할을 담당하고 있는 보체계에 대하여 양성대조군 PSK에 준하는 우수한 활성이 농도 의존적으로 나타났다. 또한 GTE-0을 처리하고 검경 시 형태적으로 구분이 가능한 활성화된 대식세포의 숫자가 증가되는 경향을 보였다. 대식 세포의 NO, ROS 및 H₂O₂ 생산에 미치는 GTE-0의 효과를 검토한 결과 ROS와 H₂O₂는 모두 농도 의존적으로 생산량을 증가시키는 우수한 활성을 나타낸 반면, NO의 생산능은 1,000 mg/mL의 고농도에서보다 오히려 100 mg/mL의 저농도에서 더 우수한 활성을 나타내었다. 또한 GTE-0으로 자극한 대식세포는 무처리 대조군에 비해 IL-6, IL-12 및 TNF-α와 같은 다양한 cytokine들의 생산이 농도 의존적으로 증가되는 경향을 보였다. 대식세포의 식작용 활성을 측정한 결과 무처리 대조군에 비해 GTE-0 100 mg/mL 농도 이상 처리하였을 때 우수한 활성을 나타내었다. 또한 활성화된 대식세포의 YAC-1 종양세포주에 대한 치사 활성을 ex vivo로 측정한 결과 100 mg/mL의 농도에서 무처리군 대비 유의적으로 높은 치사 활성을 보였다. 이상의 결과로부터 녹차 성숙잎으로부터 분리된 효소 처리 조다당 GTE-0은 강력한 면역 활성 증진 효과를 갖고 있음을 결론지을 수 있었다. In order to develop new immuno-stimulating ingredients from mature leaves of green tea, crude polysaccharides were isolated from pectinase digests of tea leaves (green tea enzyme digestion, GTE-0), after which their immuno-stimulating activities and chemical properties were examined. GTE-0 mainly contained neutral sugars (54.9%) such as glucose (14.2%), arabinose (12.2%), rhamnose (11.1%), and galacturonic acid (45.1%), which are characteristic of pectic polysaccharides. The anti-complementary activity of GTE-0 was similar to that of polysaccharide K (used as positive control). Number of morphologically activated macrophages was significantly increased in the GTE-0-treated group. GTE-0 significantly augmented H₂O₂ and reactive oxygen species production by murine peritoneal macrophage cells in a dose-dependent manner, whereas production of nitric oxide showed the highest activity at a dose of 100 μg/mL among all tested concentrations. Murine peritoneal macrophages stimulated with GTE-0 showed enhanced production of various cytokines such as interleukin (IL)-6, IL-12, and tumor necrosis factors-α in a dose-dependent manner. Further, GTE-0 induced higher phagocytic activity in a dose-dependent manner. In ex vivo assay for cytolytic activity of murine peritoneal macrophages, GTE-0-treated group showed significantly higher activity compared to the untreated group at an effector-to-target cell ratio of 20. The above results lead us to conclude that polysaccharides from leaves of green tea have a potent immuno-stimulating effect on murine peritoneal macrophage cells.
